Report on the Compressed Air Energy Storage (CAES) Market and its Contribution to Sustainable Development Goals

Executive Summary: Market Projections and Sustainability Alignment

The global Compressed Air Energy Storage (CAES) market is projected to experience significant growth, expanding from an estimated USD 0.48 billion in 2025 to USD 1.88 billion by 2030, reflecting a Compound Annual Growth Rate (CAGR) of 31.4%. This expansion is fundamentally driven by the global imperative to meet Sustainable Development Goals (SDGs), particularly SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action). CAES technology is a critical enabler for the transition to a low-carbon economy by providing long-duration energy storage, which is essential for grid stability and the large-scale integration of renewable energy sources.

CAES Technology’s Role in Advancing Sustainable Development

Technological Segments and Environmental Impact

The CAES market is segmented by technology type, with each contributing differently to sustainability objectives.

• Adiabatic CAES: This segment held the largest market share in 2024. Its design captures and reuses heat generated during air compression, eliminating the need for fossil fuels in the expansion phase. This high-efficiency, zero-emission process directly supports SDG 7 by promoting clean energy technology and SDG 13 by mitigating climate change.
• Diabatic CAES: Traditional systems that may use external fuel sources for reheating the air.
• Isothermal CAES: An emerging technology aiming for higher efficiency by maintaining a constant temperature during compression and expansion.

The market’s strong preference for adiabatic systems underscores a commitment to fully decarbonized energy storage solutions, aligning with global climate targets.

Primary Applications Supporting the Clean Energy Transition

The application of CAES technology is central to achieving a sustainable energy infrastructure, as outlined in SDG 9 (Industry, Innovation, and Infrastructure).

1. Renewable Energy Integration: As the largest application segment, CAES directly addresses the intermittency of solar and wind power. By storing excess energy and releasing it during peak demand, CAES facilitates a reliable supply of clean energy, accelerating progress toward SDG 7.
2. Grid Management and Resilience: CAES enhances grid stability and flexibility, providing essential services that support the modernization of energy infrastructure. This function is crucial for building resilient systems capable of handling high percentages of renewable energy, contributing to both SDG 9 and SDG 11 (Sustainable Cities and Communities).
